ArrARArus ron UTILIZING me HEAT or coke-cakes.

To all whomit may concern:

Be it knownthat I, CARL SEMMLER, acitizen of the German Empire, residingat lViesbaden, "Germany, have invented new a and useful Improvements inApparatus for Utilizing the Heat of Coke-Cakes, 'of which the followingis a specification.

This invention relates to a novel apparatus for utilizing the heatinherent in the able amount of heat is wasted. According to the presentinvention this heat is recovered by discharging the coke cakes from theoven into a jacketed chamber the double walls of which are cooled by aheat absorbing agent such as water. The latter ispreferably sentthroughthe jacket under a comparatively high pressure and after havingtaken up the heat, is conveyed to an accumulator to give up its heat inthe form of utilizable steam, the gases formedtluring the cooling of thecoke being carried away through a separate discharge duct. The steamthus generated may either be directly used for power or heating purposesor it may be otherwise employed. By the above described method, the heatinherent in the fresh coke is not only effectively recovered, but theresulting coke is obtained in a perfectly dry state and in the form ofcomparatively big lumps, distinguished from the coke hitherto obtainedby the absence of coke dust. At the same time, the entire process may becarried out in a more economicalmanner, because any repairing of thequenching devices, caused by the acid produced, is obviated.

In the accompanying drawing: Figure 1 is a diagrammatic sectionalelevation of an apparatus for the utilization of the heat of fresh cokeembodying my invention; Fig. 2 a similar elevation of modificationthereof; Fig. 3 a horizontal cross section through a modified form ofthe cooling chamber; Fig. 4 a longitudinal section of Fig. 3; Fig. 5illustrates diagrammatically a coke conveying mechanism constructedaccording to my invention; and Fig. 6 shows the coke discharging means.

It may here be stated that in the several figures, the pipes for thecold heat carrier,

for thehot carrier and for the steam are re spectivelyindicated by full,dotted and dot and dash lines.

The coke cake a, after being ejected from the coking chamber, isintroduced into a cooling receptacle 2), provided with a double-' walledinsert 0. The space 0 formed between the walls of the insert, is by pipef connected with the lower portion of a heat vaccumulator or vessel 6and by pipe g with the upper portion thereof. The heat carrier 0?, suchas distilled water or any other liquid incapable of forming segregationsis, by pump 7, withdrawn from accumulator e .and forced into .jacket 0while the heated carrier is returned to accumulator 6 through pipe 9,thus forming a cycle. The pump f should feed the carrier with such aspeed through jacket 0 that any formation of steam in the same, iseffectively prevented, for which purpose, pipe 9 is advantageouslyprovided with a back pressure valve 9 so that a certain overpressure maybe created within jacket 0 that effectively prohibits the generation ofsteam therein. After the carrier has passed said valve its pressure isrelieved so that a lively formation of steam is effected which may beconveyed through pipe 72, to a suitable engine or other steam consumingappliance i. The condensates formed in the latter, are'either returnedto accumulator e, or they are conveyed through pipe is and pump k intojacket 0 as illustrated in Fig. 1, thus completing the cycle of the heatcarrier. The gases generated during the cooling of'the coke withinreceptacle b are preferably carried off through a tube 0 to be eitherpermitted to escape into the atmosphere or to be collected for anysuitable purposes.

In lieu of directly utilizing the heat carrier in the heat consumingapparatus 2', it may be employed for creating another cycle for whichpurpose, accumulator e cooperates with container Z filled with avaporous fluid. The heated fluid is through pipe 71. conveyed to engine2', while the condensate formed is through pump 10 and pipe k returnedto container Z.

It is immaterial in which particular way the cooling chambers for thecoke are constructed, a condition being however that their jackets arepassed through by the heat carrier under pressure, so as to prevent theformation of steam and cause the latter to take place in the accumulatoronly. it would of course also be possible to permit the generated steamto escape into the atmosphere, or to condense the same by cooling it byan air or Water current Without departing from the spirit of myinvention, but it is obvious that such a partial carrying out of mymethod would be highly unprofitable.

In Figs. 3 and 4 thecooling chamber is 7 shown to consist of a bottomplate or base m 10;

upon which is removably supported a hood n jacketed as at 0 VThese-bipartite cooling chambers have the advantage that the-hood whichpreferably alone is provided with a 'coolingjacket, may, by a doublehose 7) be'connected to a fixed double pipe line (7 for admitting andWithdrawing the heat carrier (Fig. 5). After the temperature of thecokecake has been sufiiciently reduced, hood n'is removed from bottomsection m,

and is shifted laterally.- lhe coke cake is thus permitted to spreadupon bottom m, and may be conveyed to a carriage or its place'ofutilization by suitable means 8.

said fluid through said jacket, and pressurecontrolling means adapted tobe passed by the fluid subsequent to its passage through the jacket formaintaining the pressure of the fluid inclosed within said jacket at aheight that precludes its vaporization,

while permitting such vaporization of the fluid after its passagethrough such pressure-controlling means.

2. Apparatus for cooling coke comprising a receptacle having a jacketand adapted to receive a charge of glowing coke, the re ceptacle-jacketbeing adapted to receive a heat-absorbing fluid, means for conveyingsaid fluid through'said jacket, and a back pressure valve adapted to bepassed by the fluid subsequent to its passage through the jacket formaintaining the pressure of the fluid inclosed within said jacket at aheight that precludes its vaporization, while permitting suchvaporization of the fluid after its passage through said back pressurevalve.

3. Apparatus for cooling coke comprising a base, a jacketed hoodremovably supported thereby, stationary pipe lines for conducting a heatcarrier, and means for connecting the hood-jacket to said pipe lines.
